The Sonel UV-260 is an ultraviolet (UV) corona camera that detects, pinpoints and registers flash-arc corona and arcing partial discharge. The UV-260's high sensitivity to UV signals allows the instrument to detect UV emissions in full daylight from near or distant sources. Using non-destructive testing technology makes the Sonel UV-260 an ideal predictive maintenance instrument for overhead transmission lines and high voltage substations. UV radiation emissions are exposed on the UV-260's 5.7-inch color LCD touch-screen. Once the UV radiation is detected, the user can snapshot or record a video for further analysis.
